题目说明
编写 function solution(events, threshold, cooldownMs)。输入输出均为 JSON 值，不要修改输入数组或对象。不支持外部库、网络访问及异步函数。 events:{timestamp:nonnegative integer,ok:boolean}[] in nondecreasing time; threshold:positive integer; cooldownMs:nonnegative integer. Initially closed with zero failures. Reject while timestamp<openUntil without changing state. At/after expiry reset to closed and zero failures before accepting. Accepted success resets failures; failure increments them and reaching threshold opens until timestamp+cooldownMs. Return {accepted,state:'open'|'closed'} after each event. Zero cooldown is valid. 输入范围：每个输入数组最多50,000项，每个字符串最多1,000个字符。数字必须有限，整数及整数累计结果在JavaScript安全整数范围内。其他类型和有效性遵循上述规则。
